Abstract

An embodiment of the invention provides an alpha beta filtering based ship target tracking processing method. The alpha beta filtering based ship target tracking processing method comprises the following steps of enabling a processor to establish a predication port door according to a plotting target position which is corresponding to an original plot, the course and the speed; identifying track targets inside the predication port door; judging whether the number of the track targets is larger than 0 or not, if so, determining that the original plot is a tracking target exists and judging whether the the number of the track targets is larger than 1, if so, selecting an optimal track target to relate to the original plot if the number of the track targets is larger than 0, adopting an alpha beta filtering to relate to the original plot if the number of the track targets is equal to 1, if the number of the track targets is not larger than 0, determining that the original plot is that a tracking target does not exist, performing straight-line extrapolation on the track targets and relating to the original plot. The alpha beta filtering based ship target tracking processing method achieves comprehensive analysis and processing of various conditions and enables a track target tracking result to be accurate.

Description

Technical field [0001] The embodiment of the present invention relates to the field of computer science, and in particular to a method for tracking and processing ship targets based on αβ filtering. Background technique [0002] Ship tracking refers to real-time monitoring of the ship's location through technical means, so as to achieve remote real-time tracking of the ship's safe production and schedule execution. Real-time tracking of ships has very important commercial value. On the one hand, shipping companies, charterers and other ship operators can remotely monitor the real-time dynamics of the ship, so that they can understand the safety management of the ship and the execution of the schedule. On the other hand, for the port management agency, it can realize all the monitoring of ships in the port area, which facilitates better arrangement of operation plans and guarantees the safety of the port area. In addition, ship service auxiliary industries such as ship agency co...
